Adaptive semi-fragile watermarking based on complete quantization and image contents
Complete quantization principle is proposed in this paper,based on which,an adaptive semi-fragile watermarking algorithm based on image contents is proposed.The algorithm uses the low frequency sub-band to construct watermarking related to the content of image,and then uses just noticeable difference of wavelet domain to embed watermarking by means of complete quantitative principle.Experiments show this algorithm can classify malicious and non-malicious manipulations accurately.
